pin will transfer the contents of the data bus (D0-D7) from
the external CPU to an internal register that is defined by
address bits A0/A2.

I
Reset. (active high) - A logic 1 on this pin will reset the
internal registers and all the outputs (Also see signal RST).
The UART transmitter output and the receiver input will be
disabled during reset time. (See 155X External Reset
Conditions for initialization details.)

O
Reset output (active high). This function is associated with
the 28 pin ST16C1551 and the 48 pin ST16C1550/51
packages only. This function provides a buffered RESET
output that operates in two modes. The modes are config-
ured by IER bit-5. When IER bit-5 is a logic 0, the standard
reset mode is selected and RST will follow the logical state
of the RESET pin (see RESET). When IER bit-5 is a logic
1, the special mode is selected. During special mode
operation, the user may send software (SOFT) resets via
MCR bit-2. This is useful when the user desires the capabil-
ity of resetting an externally connected device only. During
special mode operation, soft resets from MCR bit 2 are
ORd with the state of the input pin, RESET. Therefore
both reset types will be seen at the RST pin.

I
Crystal or External Clock Input - This function is associated
with all packages types except the 28 pin ST16C1551,
which must have external clock (see CLK). Functions as a
crystal input or as an external clock input. A crystal can be
connected between this pin and XTAL2 to form an internal
oscillator circuit. This configuration requires an external 1
M
resistor between the XTAL1 and XTAL2 pins. Alterna-
tively, an external clock can be connected to this pin to
provide custom data rates (see Baud Rate Generator
Programming).
